Yesterday might’ve been the “best day ever” for Suri Cruise, but it seems her mom, Katie Holmes, struggled to get through it.

We reported earlier how the mother-daughter duo hit up Alice’s Tea Cup restaurant in NYC with some of Katie’s friends. Now, we’re hearing that everything wasn’t all sunshine and whimsical times for Tom Cruise’s ex!

An onlooker reveals that at one point during the lunch, Katie had a 15 minute chat on her phone in a corner of the restaurant and seemed “flustered and upset” while speaking.

Oh no…we wonder who she could’ve been talking to?? Could it have been Tom?!

Holmes soon dried her eyes and returned to the table after the intense convo.

The witness says Katie put on a brave face and a “big smile” for Suri, before heading to the giftshop to cash in on some souvenirs for her six year old.

So sad! Stay strong, gurl!

We hope Katie is doing alright but are glad that she didn't get upset in front of her daughter. It sounds like she's doing a pretty good job of shielding her from all of the mess that is going on!

Probably another bogus story, but if true, it just means that everybody (starting with Perez and even ordinary people) is hounding her. (Don"t start with "oh! she's a star, a public figure, etc." She really needs to be able to go to a restaurant WITH HER KID without people examining everything she does. When will people start reading her lips ?

Re: poodlewithamohawk – Honestly. All the speculation we're being bombarded with is a bit one-sided; I'm actually pretty suspicious that there are other factors at play in this divorce thing and that Holmes has been directing a smear campaign to get the upper hand (Tom's weirdness isn't helping him much). Suri needs BOTH of her parents, and I think Holmes should knock it off, stop with the drama, and get down to the business of making as CLEAN a break as she can so that Suri will benefit the most. I kind of understand her approach but I don't respect it. The one thing I'm most aware of is that none of us knows what's gone on between those two except those two, and that there are at least two sides to every story. Perez could stand to learn that … but a part of me does hope that once the divorce is over, he turns his attention to the utter destruction of Perez.

Well. Scary Scientologist and Egomaniac 'only I can save the world' Tom Cruise might be part of the stress. Read about 'missing/disappeared scientology wives, members etc…. and let's hope that Katie and Suri are able to be protected from this CULT.

Good for her for getting Suri away from this cult, and I think she planned this out very well. As far as her"melting down" I do not really see it but she is surely entitlted after all she has gone through.

A new Bill Cosby accuser's story of how he allegedly sexually assaulted her after drugging her drink is horrifying.

According to Patricia, -- who decided to keep her last name anonymous -- Bill invited her to a dinner party in 1978 after they met at a conference... a dinner party that ended up just being the two of them:
